This year, like the previous one, I've been invited to the Italian JoomlaDay that will be help in Milan on November 8th.
During my session I'll try to provide a quick introduction about developing and distributing commercial extension for Joomla!. Where you should start, which step are required to have a full automated selling site, which issues you could face everyday.
A video of the talk should be available, it will be uploaded with the slides as soon as possible.
UPDATE: Video and slides are available! Please go to the full article to view them.
